That's an interesting approach sean. Although I'm not sure if bandit lord and warlord want to be Champoin focused.
I think there should at least be additional unit bonuses.
For me, Warlord seems to mean commanding an army from the frontlines.
(bandit lord, on the other hand, can do the Assassin Path thing because honestly I don't see why they have that profession available .. and I think it should be more than just 2 starting units if thats how they want to play it)
But what about Champions that start with one of these paths? Is that a nerf to them? (indirect nerf, but still).
I like how the Sovereign's merchant profession doesn't just give +3 gold but also -25% unit maintenance.
If Warlord was to give an experience bonus, I think it'd be flavorful if that bonus was only while fighting faction troops ... then Adventurers could get experience bonuses while fighting quest related monsters.
By the way, has anyone figured out how to defeat an army of dragons? I think my 0.77 army would be able to do it ... but nothing in 0.8+ seems to do the trick (yet)
